duplicate key value violates unique constraint pg_default_acl_role_nsp_obj_index

Hi!

I have used script below to remove all rights from user and add some. Today it starts to throw error ERROR:  duplicate key value violates unique constraint "pg_default_acl_role_nsp_obj_index"

DETAIL:  Key (defaclrole, defaclnamespace, defaclobjtype)=(30152, 186783649, r) already exists.

How to fix this and which is proper way to implement this ?
